Yep, I couldn't agree more. I love the Vita, but as I've said countless times, it's "failure" is due to Sony's incompetence and unwillingness to give it the support it truly needs.
The writing has been on the wall for the longest time, sadly.
Sony, even with their successful PSP, never gave it proper first-party support, and relied entirely on third-parties and the sales boost contributed by the fact that PSP was pirate-heaven.
Sony, unfortunately, doesn't have the IPs, and the development resources to support console and handheld with the same balance that Nintendo can.
Their IPs are all too 'console-driven', where it's associated as console titles first-and-foremost, instead of being handheld-driven like say, Fire Emblem, Pokemon or Animal Crossing. It's hard to build a system seller driven around console-focused franchises because sales would gravitate on their superior console version instead of a washed down handheld version.
Developmental resources is a no-brainer. None of Sony's core teams are actively developing for handhelds.
